The Capability Maturity Model (CMM) was created by Carnegie Mellon University to ensure software development contractors had adequate processes. CMM evaluates and improves an organization’s processes through five levels of maturity, with the highest level focusing on continuous improvement. CMM is used in information technology management and has been replaced by the Capability Maturity Model […]
A host model acts as a gatekeeper for networked computers, accepting or rejecting data packets. IP addresses are used to send packets to specific hosts. Strong host models require more validation than weak models, which can improve network connectivity but make it easier for hackers. Some systems use an “rp_filter” option to increase security. A […]
Adaptive models are used by data analysts to predict outcomes in changing contexts. They are created using software and include factors such as resources, demand, and time frame. They can be used in various fields, including network security to detect cyber-attacks. An adaptive model is a way to visualize data that can evolve with the […]
Data warehouse models are used to build physical applications of computer system data models. There are several types, including Flat, Hierarchical, Relational, and Dimensional. Relational and Dimensional models are the most common, with other types being minor improvements to the basic methods of organizing. A data warehouse model is an applied form of a computer […]
The spiral model is a four-step process for software design that repeats until completion. It starts with planning, followed by finding ways to complete objectives quickly and safely, programming features, and testing with the customer. The process repeats until the software is ready for distribution or completed to customer specifications. The spiral model is a […]
The spiral model is a four-step process that repeats until software is complete. Developers discuss goals, find ways to complete objectives, program features, and show the customer for acceptance or rejection. Planning, discussing features, programming, and testing are the four steps. The spiral model is a software design philosophy that, instead of being a linear […]
Creating a logical data model (LDM) is the second step in database development after the conceptual data model (CDM), showing important data and relationships between tables. The LDM is detailed with titles and relationships but no actual data, making it easier for engineers to build the physical data model (PDM). In systems engineering and database […]
An acoustic model is a map of voice in relation to printed words used in speech recognition programs. It is one of two main files needed, along with a language model. Speech recognition software requires a microphone and sound processing program. Acoustic models can recognize variations in pronunciation and interpret multiple languages. Computational linguistics is […]
Data mining extracts and presents data from large sets, often used in business intelligence. Regression, association, factor analysis, and categorization are common models used to analyze data and find relationships and trends. Data mining describes the process of extracting data from large sets of information and presenting it in a unique way. This process is […]
DCOM is a Microsoft technology that allows software components to be distributed across multiple servers, enabling enterprise-wide scalability. It was introduced in the late 1990s and is used primarily by organizations using Microsoft products. However, it requires the use of Microsoft technology to function properly and has been largely replaced by more flexible web services […]
The Data Reference Model (DRM) is an XML-based system that standardizes data entered by US federal agencies, allowing for easy sharing and retrieval. It is part of the Federal Enterprise Architecture and includes a Community of Interest (COI) for sharing data with non-governmental bodies. The DRM promotes easy retrieval through standardized data descriptions, categorizations, and […]
A domain model is a visual representation of a problem in software engineering, breaking it down into component parts. Flowcharts are a good representation. It defines key concepts and vocabulary and links classes logically, leading to clearer and more concise code. A domain model is a schematic overview of a specific problem used in the […]
The relational model is a widely used database framework based on predicate logic. It was developed by Dr. Edgar F. Codd in 1969 and uses SQL to query data. The model is flexible, easily updated, and can be accessed by many applications. The relational model is a simple, yet concise, framework for database storage, retrieval, […]
Becoming a part-time model doesn’t require a specific level of education, but taking modeling courses and creating a diverse portfolio is recommended. Part-time models can offer free services to photographers to build their portfolio and then send it to companies looking for models. It’s important to keep track of earnings for tax purposes. Take a […]
The prototype model in software engineering involves building software using code snippets from a library, improving productivity and reducing development time. It allows for variation in code and eliminates much of the testing required in traditional development. This method also benefits consumers with lower prices and faster releases. Prototype model is a software engineering term […]
Choosing the right quantitative analytics model depends on the field and questions being asked. Financial professionals might use technical analysis, market researchers assign numerical values, and computing professionals monitor automated systems. Knowing the desired outcomes is important. Outcome logic design helps make strategic decisions, while needs-based assessments interview stakeholders to determine demand. Consult with all […]
The Standard Model of particle physics describes particles and their interactions through three fundamental forces. Fermions and bosons make up particles, and the model predicts outcomes of particle interactions. The Higgs boson and graviton are hypothetical particles, and gravity is not included in the model. If the graviton is discovered, it could replace the Standard […]
The entity-attribute-value model allows for a restricted set of attributes to be selected from a larger list, reducing unused data variables and allowing for easy addition of new attributes. It also provides flexibility in data modeling and may require metadata for effective use. An entity-attribute-value model is a method of representing a collection of data […]
The entity-attribute-value model allows for a restricted set of attributes to be attached to an entity, reducing unused data variables and allowing for easy addition of new attributes. It provides flexibility in data modeling and can be used alongside traditional relational structures. Metadata is necessary for effective implementation. An entity-attribute-value model is a method of […]
A computer database is organized in tables with a parent-child relationship. A network model database allows for multiple parent and child tables, resulting in a more natural graphical structure. It allows for a more realistic representation of the relationship between tables, but is largely obsolete in modern database design. Relational databases allow end users to […]
